Guide to Tipping
I keep about 15 different valve guides next to my valve-refacer to use when “tipping” the valve stems. By clamping the guide into the machine instead of the stem of the valve, I can easily insert the valve and use two fingers on the head of the valve for pres- sure while grinding the tip of the stem. This makes grinding the tips for valve adjustment clearance much faster than clamping the stem each time. For efficiency keep a good selection from 5mm to 7/16” I.D. close to the stem size.
